Almost every summer since 2016, young archaeologists from Phillips Academy’s summer session program embark on a mission to excavate the site of the eighteenth century Samuel Philips Jr. Mansion House, located on the West Quad of campus. The infamous Mansion House was built in 1782 by the academy’s founder and stood for 105 years, before burning down in 1887. News articles from the period suggest that the demise of the Mansion House was a result of arson; many speculating that the proprietor, Charles Carter, started the fire. During its long period of occupation, the Mansion House served as not only a home, but later an inn and tavern for students, community members, and travelers. The site’s long history and relatively undisturbed context creates an ideal setting for archaeological excavation and student learning.
Over the past seven years, students have succeeded in discovering portions of the house, including multiple chimneys and a basement feature. This year, students set out with high expectations, choosing to place four excavation units in spaces just outside of the Mansion and two units in the southwest portion of the quad, near the sites of historic outbuildings, a nineteenth century printing house, and an early nineteenth century pathway.
Students in each excavation team had a blast taking turns performing the primary tasks of an archaeologist: digging, screening, measuring, and note-taking. Many, if not all, students even got to unearth artifacts from their units! Some of our favorites included a small ferrous key, an impressed glass tumbler, and half a pair of scissors which all came from the two excavation units placed in the southwest portion of the quad.
Further excavation in this area revealed a feature relating to the historic pathway present on early nineteenth century maps of campus. Pictured below is a dense, gravelly layer of soil discovered at 40 cm. This layer, interpreted here as the pathway, was intermixed with nineteenth century materials including glass, brick fragments, and some ceramic.
Students excavating the other four units in the northern portion of the quad found shallow cultural layers followed by a sterile C horizon, between 20 and 35 cm. While the artifact density of these units was limited, students still enjoyed finding an abundance of brick, metal nails, and some small ceramic fragments. The very shallow deposits found in these units informed the team that no building activity likely occurred in these areas. Additionally, the relatively low artifact density suggests that these areas were not regularly used like in a dooryard or garden area.
Overall, students in the 2025 field program successfully applied archaeological methods to ‘unlock’ more of the mysteries surrounding the Samuel Phillips Jr. Mansion House. This year’s field season serves to inform of the deep cultural deposits in the southwest portion of the quad and the significant research potential it could provide for future field seasons.
Thanks to the entire student field crew and cheers to a wonderful field season!
